Updating this because it’s been a while! We still haven’t added this to our roadmap.
As we mentioned we’ve found in testing that this behavior ends up confusing people, which is why we’ve chosen not to add it so far.
We’ll continue to leave this under review for further voting and comments.Rhiannon Batstone commented
Perhaps add it as an optional feature like the simplify group debts option?
Otherwise it seems somewhat pointless to even have the ability to add a future date
